Supply spherical alumina powder as thermally conductive filler

Product Performance

Spherical alumina as a thermally conductive filler can significantly increase the thermal conductivity of the mixture, reduce the expansion coefficient, and increase the strength of the mixture. The spherical shape is conducive to the dispersion and sliding of the powder in the system. It can be evenly dispersed in the organic body and form the closest packing to obtain a mixture with high filling, low viscosity and high thermal conductivity. Spherical alumina greatly reduces the wear of mixers, molding machines, molds and other equipment, which can extend the service life of equipment.

Specification of spherical alumina powder:

CAS No:1344-28-1 ENINEC No.:215-691-6

Note: We can supply different size products of high purity alumina according to client's requirements.

Application of spherical alumina powder:

1. Thermally conductive gasket, thermally conductive silicone grease, thermally conductive potting compound, filler for heat dissipation substrate, thermal phase change material, etc.;
2. Filler for semiconductor packaging resin;
3. Silicone heat dissipation adhesive and filler for mixture;
4. Epoxy molding compound, epoxy castable filler, thermally conductive aluminum substrate, etc.

Storage conditions:
spherical alumina powder should be sealed and stored in a dry and cool environment. It should not be exposed to the air for a long time, to prevent agglomeration due to moisture, affecting the dispersion performance and use effect, and should avoid heavy pressure, do not contact with oxidant, and transport according to ordinary goods.
